From this , about 1750 , the spectroscope was developed .
大约在1750年,据此发展了分光镜。
These composites are of interest to engineers in their own right , but when dr broomell and dr waite stuck ragworm jaws in an x-ray spectroscope they found no sign of mineralisation at all .
不过当布鲁梅尔博士跟瓦特博士将沙蚕颌齿放到分光仪里时,他们连一丁点的矿化迹象都没发现到。
It would be obvious to anyone who turned a spectroscope on earth , for example , that something odd was going on . Air that is 21 % oxygen , one of the most reactive elements in the periodic table , suggests the gas is being freshly minted-as it is , by photosynthesis .
